Re: UPX 5.0.1
Unfortunately, this is a problem with most antiviruses and there is nothing that we can do other than reporting these false positives to them. 
Anyway, I'm using --lzma with EXEs for best compression.

Re: UPX 5.0.1
Good afternoon Hua, this does not happen with PECOMPACT.exe, as it "INVOKE" the digital signature of the Anti Virus: AVG.exe Free or Paid, for example.hua wrote: Wed Jun 11, 2025 4:35 am Enrico,
what flag do you use with upx because my exes frequently got flagged with false positives from anti-virus scanners
TIA
Buenas tardes Hua, esto no sucede con PECOMPACT.exe, ya que "INVOCA" la firma digital del Anti Virus: AVG.exe Gratis o de Pago, por ejemplo.

Re: UPX 5.0.1
I tried PECOMPACT: smaller compression and same false positives (at least with Windows 11 Defender).

Re: UPX 5.0.1
Good afternoon Enrico. If you test with a better quality Anti Virus such as: NORTON.exe, AVAST.exe OR AVG.exe, you will see that this will not happen. I do not recommend Windows Defender, it causes a lot of problems. I use AVG.exe and it is excellent!Enrico Maria Giordano wrote: Wed Jun 11, 2025 3:49 pm I tried PECOMPACT: smaller compression and same false positives (at least with Windows 11 Defender).
Buenas tardes, Enrico. Si pruebas con un antivirus de mejor calidad, como NORTON.exe, AVAST.exe o AVG.exe, verás que esto no ocurre. No recomiendo Windows Defender, causa muchos problemas. Yo uso AVG.exe y es excelente.

Re: UPX 5.0.1
Don't force it. Just RECOMMEND it as I do. I usually ask the IT professionals in the company to test AVG.exe and decide on their own free will to replace Windows Defender with a better Anti Virus.Enrico Maria Giordano wrote: Wed Jun 11, 2025 4:57 pm You missed one point: I cannot force my users to change their default antiviruses.
No lo fuerces. Simplemente, recomendámelo, como yo lo hago. Suelo pedir a los profesionales de TI de la empresa que prueben AVG.exe y decidan por iniciativa propia si reemplazar Windows Defender por un antivirus mejor.
Gracias, tks.
By the way: with this version of UPX5, AVG.exe did not report false positive using: --lzma. ok?
Por cierto: con esta versión de UPX5, AVG.exe no reportó falsos positivos al usar: --lzma. ¿ok?

Enrico, te pido disculpas. El Traductor de Google no expresó exactamente lo que quería decir. Si no entiendes algo, el problema está en la traducción del Traductor de Google, ¿de acuerdo?
Enrico, I apologize. Google Translate didn't express exactly what I wanted to say. If you don't understand something, the problem is with the Google Translate translation, okay?
Gracias, tks.

Re: UPX 5.0.1
No problem, what you wrote is perfectly clear. But I cannot recommend AVG because I don't like it. I prefer and recommend the standard Windows Defender antivirus.
